SPOILER
In reply to an earlier thread, on level 12 you go high with the bird and only split it when you are very close to the top ice sheet. If done well you should blow up the TNT and get all the bottom clear and one of the sides, sometimes you leave both the sides. Then you just clean up with one more bird.
Level 13 is hard, but I did it by splitting the bird early and the top split of the bird should get the TNT to fall, the bottom birds should clean up the left pigs. The TNT will kill the middle then the helmet pig will slowly roll to the left and then die. It is possible to do the level with one bird if done perfectly. Takes a long time though.
